RWD Retrofit

Allows an existing "desktop site" to co-exist with a "responsive site", while also able to serve the desktop site to a different breakpoint on "mobile"

It's also able to serve the desktop site to a different breakpoint on mobile touch devices - useful for serving the desktop site to tablets, for example

Returns an object containing the desktop (rwdRetrofit.desktop) and optional mobile (rwdRetrofit.mobile) media queries as strings for responding to media queries with JS; for example, by using enquire.js (http://wickynilliams.github.com/enquire.js)

---

Usage:

1. Set up the viewport with: <meta name="viewport" content="width=device-width, initial-scale=1" />

2. Reference the existing desktop stylesheet in a <link> with a relevant media query, eg. media="all and (min-width: 990px)" and class="rwdretrofit-desktop"

3. Reference the new responsive stylesheet in a <link> with a relevant media query, eg. media="all and (max-width: 989px)" and class="rwdretrofit-mobile"

4. Add an optional data-breakpoint-width="xxx" attribute to the desktop stylesheet <link>, where xxx is the pixel-width that the desktop breakpoint will occur on mobile devices - eg. 768 for iPads and other large tablets

5. Add an optional data-viewport-width="xxx" attribute to the desktop stylesheet <link>, where xxx is the pixel width that the desktop viewport will be set to on mobile devices

6. Add an optional data-debug="true" attribute to the desktop stylesheet <link> to force non-touch devices to use the data-breakpoint-width override
